I have recently updated Tableau Server to 2018.1 from 10.5.3. Since that, Trusted Autentication is not working properly. I am able to get a ticket and use it in an url to get the dashboard but when I what to interact (for example clicking on a pie) I get this message:

An error occurred communicating with the server (500).

This may be a temporary network condition. Please retry the operation.

I have tried to reset the trusted list of IPs via the tabadmin set command with no success. I am still experiencing this issue. I am putting in a ticket with Tableau Support and will reply back with useful information.

Currently, I have a core server license and use trusted ticketing to display views on our public website and I control the permissions with a single service user. From what I can find about changing this is it will give full access to the UI? How does this work exactly? Could someone get the ticket and see all content that the user has access to? When does the ticket expire?

1. Trusted tickets only allow access to views and not to the Tableau Server UI. This means that redemption of a ticket doesn't allow any TS UI/vizportal functionailty, just using views.

2. Unrestricted trusted tickets give full access to the server as the user the ticket was requested as.

3. If someone was to gain access to the machine requesting trusted tickets they could request a trusted ticket as the administrator, redeem it, and have full access as an administrator to the server. This is one of the reasons trusted tickets only allow specific IPs and not ranges of IPs for adding to trusted hosts to request tickets.

4. This full session is good for the length of time that wgserver.session.idle_limit / wgserver.session.lifetime_limit are to (default no more than 240 minutes of inactive use).

If you believe that you have secured your environment enough that #3 is not a concern, unrestricted tickets is a workaround. However, you are choosing to open the door to your server much wider than it otherwise would be.

The fix is currently targeted at our next maintenance release for 2018.1 and we do those maintenance releases about once a month. We're still finishing the maintenance release but if we don't run into any problems i'd expect you'll see the release before the end of the month.

In Tableau Server 2018.1 after initial load, any interactions with an embedded view accessed using trusted authentication would result in a repeated error: An error occurred communicating with the server (500)
